DN 15 refers to the pipe diameter, also known as the nominal diameter of the pipe. DN is nominal, which means nominal, and 15 means internal diameter of pipeline15 mm. DN is usually used as a sign of pipeline so that people in different areas can understand it.

There are some technical parameters related to the water pipe DN 15, such as the pressure and flow carried by the pipeline. These parameters are determined by the material, thickness and installation method of the pipeline. Therefore, when selecting water pipes, it is necessary to consider the actual situation to ensure the safety and reliability of the pipes.

DN 15 water pipes are often used in home decoration or engineering construction, such as faucets, showers, washing machines, water supply pipes, etc. When installing, pay attention to the parameters such as the material and thickness of water pipes, and install them according to relevant specifications, so as not to affect the quality and normal use of water.
